Internal a1200 IDE interface

1MB/sec is perfectly quick enough for me!!  Reading more than a whole floppy disk in a second!!  Who could want any more than that !!  

Tension:

I agree.  And with an 030 it sounds like the original IDE interface does 2MB/sec plus.  So, it's more than a high density floppy per second!  Sounds good enough to me.

The thing is though it's not like a harddrive is constantly reading one area of a disk, so 1-2 meg is quite painful a lot of the time. Extracting/compressing large files can be quite torturous.

You're right it's not like the HD is constantly reading from the disk when extracting or compressing large archives.  Because with compressed files,  I think it's CPU cycle intensive a lot more than dependent on a particularly fast IDE interface.  Even when extracting, but especially when compressing, CPU speed is a lot more relevant than IDE and HD speed.  My experience is even when compressing files, with a utility like LZX, it is rather fast to HD.  That is, as long as it's not set to the highest compression level, which compresses to the max., at the full expense of CPU time.  Any other setting is fast on compression (though still very efficient).  And extraction is very fast.

fishy fiz:

Actually it's quite accurate, for an 030 system, that I mentioned.  It's sounds like you're talking about extracting and compressing both from and to the HD.  I usually extract to RAM, then copy the contents to disk.  In addition to a speed increase over HD, though not huge, I usually do it that way because the destination path is more manageable to control with LZX.   I haven't regularly worked with archives of 50MB+.  I guess that depends how fast you expect it to still be with archives that huge.  But I can tell you LZX is significantly faster than something like UnArc (from OS3.9).  CPU time is the slower factor with any decent amount of compression, and that's with an 030@40 and 882@50.  I don't know what CPU you're using, 060, PPC?

Franko:

I was wondering that about the SCSI.device too.  Interesting :-).

Get a 7200 RPM HDD with a reasonable cache and it will help the standard IDE.

How does a 5400RPM 8MB cache drive sound for that?

Though I'm not sure it would matter how fast of an HD it is, on my system.  I seem to be getting only around 190KB/sec (502MB in somewhere around 45min.).  An 030 should be getting around 2MB/sec. plus is what was said earlier in this thread.  I don't think this is anything new with this HD though.  I seem to remember my previous HD getting something around that poor of a speed too, I just didn't time it really or know what speed it should be getting.  2MB/sec. seems plenty fast to me, but 190KB/sec. sure doesn't.  I wonder what could be slowing things down so much?
